On Jan. 8, Tropical Cyclone Irving was hurricane-force in the Southern Indian Ocean. The Global Precipitation Measurement Mission or GPM core satellite passed overhead and measured cloud heights and rainfall rates in the powerful storm.

A new study published Jan. 8 in the journal Nature Geoscience reveals that strong El Niño events can cause significant ice loss in some Antarctic ice shelves while the opposite may occur during strong La Niña events.

NASA's Terra satellite passed over Tropical Cyclone Ava as it continued moving away from the island nation of Madagascar. Ava was located in the Southern Indian Ocean, off the southeastern coast of the country.

Human activities are exposing US rivers and streams to a cocktail of salts, with consequences for infrastructure and drinking water supplies. So reports a new study in the Proceedings of the National Academy of Sciences that is the first to assess the combined, long-term changes in freshwater salinity and alkalization across the country.

A team of researchers from the National University of Singapore (NUS) has pioneered a new water-based air-conditioning system that cools air to as low as 18 degrees Celsius without the use of energy-intensive compressors and environmentally harmful chemical refrigerants. This game-changing technology could potentially replace the century-old air-cooling principle that is still being used in our modern-day air-conditioners. Suitable for both indoor and outdoor use, the novel system is portable and it can also be customised for all types of weather conditions.
